Blood loss

I tested positive Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>, and started what I thought was implantation bleeding a week ago today, stopped for two days then started bleeding again yesterday which is now heavy. I suspect I’m losing the baby and typical the doctors won’t do anything. Surely they could test HCG levels to see if they’re dropping or what? Anyone else experienced this. Such an awful time. Lack of support is disgusting
